Dithiocarbamates and phosphite formulations
View Patent ↗Dithiocarbamate and phosphite containing fertilizers, as well as methods of making and methods of using these fertilizers, are disclosed.
1. A fertilizer concentrate comprising:
a dithiocarbamate; and
calcium phosphite,
wherein said fertilizer concentrate is essentially devoid of dispersants and wetting agents.
2. The fertilizer concentrate of claim 1 , wherein
said dithiocarbamate is in a granular form;
said dithiocarbamate is present in an amount of from about 0.55 kg of dithiocarbamate/kg of fertilizer concentrate to about 0.95 kg of dithiocarbamate/kg of fertilizer concentrate;
said calcium phosphite is present in an amount of from about 0.01 kg of calcium phosphite /kg of fertilizer concentrate to about 0.45 kg of calcium phosphite /kg of fertilizer concentrate.
3. The fertilizer concentrate of claim 2 wherein at least about 90% of the granules of said fertilizer concentrate have a diameter of from about 0.001 mm and about 0.5 mm.
4. The fertilizer concentrate of claim 1 , wherein said dithiocarbamate is a member selected from mancozeb, maneb, zineb, thiram and metiram.
5. A method of providing a fertilizer and a fungicide to a plant, said method comprising:
(a) mixing water and the fertilizer of claim 1 , thus forming a use-dilution fertilizer; and
(b) applying said use-dilution fertilizer to the foliage of a plant, thus providing said fertilizer and said fungicide to a plant.
6. The fertilizer concentrate of claim 1 , wherein
said dithiocarbamate is present in an amount of from about 10% wt of dithiocarbamate/wt of fertilizer concentrate to about 35% wt of dithiocarbamate/wt of fertilizer concentrate;
said calcium phosphite is present in an amount of from about 15% wt of calcium phosphite /wt of fertilizer concentrate to about 35% wt of calcium phosphite /wt of fertilizer concentrate
and-further comprising water in an amount of about 30% wt of water/wt of fertilizer concentrate to about 40% wt of water/wt of fertilizer concentrate.
7. A fertilizer concentrate comprising:
a dithiocarbamate, which is present in an amount of from about 10% wt of dithiocarbamate/wt of fertilizer concentrate to about 35% wt of dithiocarbamate/wt of fertilizer concentrate;
at least one phosphite salt, which is present in an amount of from about 15% wt of phosphite salt/wt of fertilizer concentrate to about 35% wt of phosphite salt/wt of fertilizer concentrate
a suspending agent, which is present in an amount of about 5% wt of suspending agent/wt of fertilizer concentrate
and water in an amount of about 30% wt of water/wt of fertilizer concentrate to about 40% wt of water/wt of fertilizer concentrate.
8. The fertilizer concentrate of claim 7 , wherein said dithiocarbamate is a member selected from mancozeb, maneb, zineb, thiram and metiram.
9. The fertilizer concentrate of claim 7 , wherein said phosphite salt is a member selected from monopotassium phosphite, dipotassium phosphite, calcium phosphite, monoammonium phosphite, diammonium phosphite, calcium hypophosphite and potassium hypophosphite.
10. The fertilizer concentrate of claim 9 , wherein said phosphite salt is calcium phosphite.
11. A method of providing a fertilizer and a fungicide to a plant, said method comprising:
(a) mixing water and the fertilizer of claim 6 , thus forming a use-dilution fertilizer; and
(b) applying said use-dilution fertilizer to the foliage of a plant, thus providing said fertilizer and said fungicide to a plant.
12. A fertilizer concentrate comprising:
a dithiocarbamate; and
at least one phosphite salt,
without the presence of dispersants or wetting agents, wherein said fertilizer concentrate is in a solid form.
